Be it'kn'own that I, ASHTON S'rAnKE, a citizen of the United States,Aresiding at Richmond, in the vcounty of Henrico and Slate of Virginia,have 'invented a new and useful Improvement in Pump Valves andCylinders,l of which the followin isa specification. n Y My invention relatestoimprovements' -in pumps-for wells5 &c.;ind the objects of myimprovements are, 'irst, t0 provide a' valveseat and valve which'may beremoved from the cylinder and: up. through the tubing of the pump"withogrt the use 'ofoutside appli-A ancesandfrendeiiwg itunnecessaryvtoeither remove rthe pu or todescend into the well for suchpurpose, and, secondly, to socon-- struct'the bottom of the cylinder as'to seff cnrely hold the valveseat andcagein their" positions.lattaintheseobjects 'bythe m'eCll' anisnr illustratedl in theaccolti-pan yingiraw-v ings, in which- Figure IY is a vertical sectionyof `the whole constructiom'each part being in its relativev position aswhen in operation.' Fig. II shows the valve-cage disengaged from thethreaded pin'which lfasten's andwholds the "said cage. downl upon theinside face of the'cylind'erf socket. Fig-III is atop view of fthevalvecage, showing thejlongor slot hole throughgo which the arrow-shapedlower end`l of the plunger-rod is passed. Fig. IV shogwslsec- 'tionalparts'of the valve-cage and valve-seat in regular order. y y

The upper part ofthis lower portionofthe'cage is threaded to receive the valve-seat J; FA' verticalcheck-valve M is shown resting l(n'x'theseat il,V whiley at O, Fig. 4'51V, is shown'v a,r projection to whichm'ay be attached av hinged valveto work on the same valve-seat, e In Figl-III at vX is shown the long orslot hole.

Turning,plunger-rod, the arrow-shaped end comes in." -contact with andpressesagainst the projce-f tions @which-'projections are so shaped andsituated as to allow the arrow-shaped lower 'end of -the plungerrod O tostandas nearfat a 6o right angle to the slot or long hole Xa'spossible.- By'turning,'then,the ,plunger-rod to the' right, say, thelowerend of the cage at E isl screwed downupon the pin Z5 andthe base ofthe cage at K is lnnade tof resten 'the projec'tioniof thecylinder-socketat Q, forming water-tightjoint.- .On the Ivother hand',by tprnngtheplunger-rod to the left thc.alrow shaped end of theplunger-rod'C isv reversed and .made to"pr.ess against'the oppositesides7o of' the projectionspr and so nnse'rews the f threadedend of thecageat E and disengagesit fromy thepin at' Z.

.the plnnger-rdand gently pulling it upward at the same time. thearrow-shaped en doncejl: again finds the long orslot hole inthe upperportion of the cage/and passes-through the I same, leaving the cage ixedin position. y

To removethe valve-seat and valvawhieh l are. located in the cage, fromthe cylinder, the- L 5 plunger-rod is turned so as to unscrew thel fcage lfrom -thepin lZ, andthe arrow-shaped end of -the plungerrodstanding nearly at right v angles to or across. the slotted-or longholeX," thecage is thus drawn or lifted up through' andout ofthecylinder and up through the tubing of the' pump. v i 1 vThe bottom ofthe cylinder-soeket'F-is pro-[9.0; vided withfa crossbar D, in whichcrossbar` is fixed and set the threaded pin Z, and the i extreme bottomof `this` cylindersocketwisv threaded to receive the' pipelywhich pipeisintended to extend down into the water.

I am aware 'thatrpumps have been made prior to my invention withwireecaged cheek or puppet Valves, which valves may be removed froxntheeylnder without the aid of l outside appliances; but in these thereis no provision for removing the valve-seat, as well as the valveitself, and, further, such Wireconstructed cage or puppetvalves arefrail and subject to easybreakage and being nent roo then., thee-'55 gso out of shape as to render them useless nor is there provision forusing a hinged as well as vertical valve.

A most important advantage possessed by my pump-valve over thosehitherto in use is the removability of the valve-seat for repairs, forthe insertion of a check-valve, and for the insertionand the secureholding of a gasket. To remove the seat\J, the lower part of thevalve-cage L is unserewed from the said seat J, which can then be slidout sidewise. To insert a check-valve whose total length is such that itwill just pass between the upper surface' of the ring K of thevalve-cage and the lower surface of the slotted top A of the saidvalve-cage, I remove thevalve-seat, as described above, slip Athe seataround the Wings of the check-valve, slide the valve, with the seat,into place, drop the seat into position, and screw into it from belowthe lower part i of the valve-cage. A gasket can be vinserted bydropping it over the upper,thread ed portion of the lower part L of thevalveeage before the latter is screwed up into the seat J. There mayhave been made valve cages or seats to screw down into the bottom of thecylinder and which depend upon one thread being less tightly screwedthan another to enable one to release the seat or valve; but in such thediameter of these seats or valves where they are threaded is so greatthat the leverage is against the operation, whereas inmyfinventionthefdiameter 'of the holding-pin is reduced to a minimum, and thus thescrewing on or off of the valve-cage isy rendered certain. y
